Packages that use IAccessPath

com.bigdata.bop	This package provides an API for query operators.
com.bigdata.rdf.inf	This package provides an eager closure inference engine for most of the RDF and RDFS entailments and can be used to realize entailments for owl:sameAs, owl:equivilentClass, and owl:equivilentProperty.
com.bigdata.rdf.lexicon

com.bigdata.rdf.store	This package provides several realizations of an RDF database using the bigdata architecture, including one suitable for temporary data, one suitable for local processing (single host), and one designed for scale-out on commodity hardware.
com.bigdata.relation	This package includes an abstraction layer for relations.
com.bigdata.relation.accesspath	This package includes an abstraction layer for efficient access paths, including chunked iterators, blocking buffers, and an abstraction corresponding to the natural order of an index.
